Abstract
PURPOSE:To accelerate processing without using a high speed clock by executing the processing which a binary image is converted to a multivalued image for plural picture elements at once. CONSTITUTION:A first memory means 11 storing the binary image of which one picture element is constituted by one bit, an enlargement means 12 enlarging each bit of the binary image supplied by the first memory means 11 to (n) bit, a second memory means 13 maintaining at least the value of the (n) bit complying with the binary image when the value of it's one bit is zero and a third memory means 14 maintaining at least the value of the (n) bit complying with the binary image when the value of it's one bit is '1' are provided. Besides, a selection means 15 which decides the information of the (n) bit complying with the one bit of the binary image obtained by being enlarged with the aid of the enlargement means 12, selects the complying bit value of the second memory means 14 when the value is '0' and selects the complying bit value of the said third memory means 14 is provided. Thus conversion from the binary image to the multivalued image without using the high speed clock, that means the binary and multivalued method and it's device can be obtained.
